In fact, it is the motor of the drum row. Electrical operation is controlled by washing machine program. It’s like a pump. The drainage of automatic washing machine has a tractor guide, open to see inside the structure is more complex than the electromagnet, there is a small motor to drive a lot of plastic gear, and finally drive the rack to pull the drain valve to release water, at the same time to shake dry bucket lock and ratchet lock loosen, ready to shake dry. There is also a small electromagnet used to lock the rack when it is pulled to the end, to prevent the rack from being pulled out by the drain valve reset spring, and the motor to withstand the strong pull of the reset spring for a long time during the drain. At the end of drainage, the tractor is powered off, the small electromagnet clamp is loosened, the rack is pulled out by the drainage valve reset spring, and the drainage valve is reset and closed. The whole process is linked, a little with the clock is not in place, there is a fault, and the inside of the gear with clock gear is almost the same, but are plastic, the most vulnerable to damage, partial factory low quality plastic is more harmful.
Drain pipe put a little higher, can not put flat, flat is not stored water. But when it’s time to drain the dirty water, it pumps it out.
